S-57 Background

• DX 87 ? DX 90
• May 1992 - IHO S-57 - formally adopted (a number
  of Edition 2 ENC cells produced)
• November 1996 - Edition 3.0 (ENC Product
  Specification Ed 1)
• Frozen four years to provide stability so that
• - HOs could produce ENC data and
• - OEMs could develop ECDIS equipment
• November 2000 - Edition 3.1 released (ENC Product
  Specification Ed 2)
• (38 new attribute values added)
• It was decided that Edition 3.1 would remain
  frozen until at least November 2002.
• January 2007 - Edition 3.1.1 released
  (Enhancements Required to Encode S-57 Edition
  3.1.1 ENC Data).
• three new feature object classes
• three new attributes, and
• two new attribute values for Category of
  Restricted Area.
• (Presently about 10 000 Edition 3.1 ENC cells)

IHO Definition of Hydrography

• That branch of applied sciences which deals with
  the measurement and description of the features
  of the sea and coastal areas
• for the primary purpose of navigation and
• all other marine purposes and activities
  including (inter alia) offshore activities,
  research, protection of the environment and
  prediction services

approved by IHO Member States in November 2002
4
Other Users

• Other communities have developed products based
  on S-57
• AML
• Inland ENC
• MIO

• Open ECDIS Forum
• Privately registered Producer Codes (not in
  S-62)
• mechanism for registering external features and
  attributes (no longer on the OEF)

5
S-57 Limitations

• Developed primarily to meet ENC requirement for
  an IMO compliant ECDIS
• Inflexible maintenance regime (freezing of
  editions)
• Cannot support contemporary requirements
  (imagery, gridded bathymetry, time-varying
  information, et cetera)
• Data transfer mechanisms are limited (data model
  embedded in encapsulation (ISO 8211))

S-57 ENC Product Specification

S-100 The IHO Geospatial Standard for
Hydrographic Data

• S-100
• - is based on ISO 191xx set of Geospatial
  Standards(ISO profiles tailored for
  hydrographic requirements)
• - will support a broader spectrum of hydrographic
  requirements
• - makes provision for imagery and gridded data
  (not in S-57)
• includes the concept of feature data
  dictionaries /catalogues (maintained within a
  registry)
• - supports the development of multiple Prod Specs
  and enables them to be maintained independently
• - supports more that one encoding format (ISO
  8211 and GML)

S-100 Publication where are we ?

• Registry has been completed and is on line
  (http//195.217.61.120/iho_registry/home.php)
• Draft S-100 components documents completed at
  TSMAD 15 (IHB Monaco - 4 to 7 Feb 2008).
• S-100 component documents are presently being
  combined into a single document and
  harmonised/cleaned, etc .. ? to be made available
  at end of February 2008.
• March to August review period (comment sheet
  will be made available for feedback).
• Comments to be reviewed at the September 2008
  TSMAD meeting and a final version prepared for
  adoption by CHRIS 20 in November 2008

S-100 Publication where are we ?

• Some key components still missing
• Portrayal component dependant on the
  availability of a stable version of ISO 19117
• Encoding application schema and encoding
  formats are being prepared for ISO 8211 and GML,
  - draft versions will be available late May 2008.

17
Additional Objectives

• Content and carrier are independent
• Core standard can evolve through extensions - no
  need for new versions of product specifications
  or system revisions
• plug and play updating
• Product Feature Catalogs more flexible and
  capable of expansion
• will accommodate future IMO regulations
• Will support emerging ECDIS / E-Navigation
  requirements (integrated Nautical Publications,
  Inland ENC Product Specs, ..)

18
Derived Benefits

• S-100 stays in mainstream of GIS ? greater use
  and lower cost of implementation
• Maximizes access to COTS software applications
  and development
• New components not developed in isolation
• Interoperability with other ISO 191xx based
  profiles (e.g. NATO, WMO (ice), )
• Encourages use of hydro data beyond HOs and ECDIS
  users (coastal zone mapping, security,)
• Plug and Play updating of data, symbology and
  software enhancements
• Inclusion of 10 years worth of deferred S-57
  corrections and extensions

19
